1. Ensure that the AC/DC input service is disconnected.
2. Install the interface cable between the host controller and the ReFlex
3. Connect an appropriate input source to the Active Load module.
4. Configure the host controller for communications with the ReFlex
5. Turn on the Mainframe AC/DC input service.

The channel number corresponds to the slot of the ReFlex Power™
Mainframe where the module is located, counting left to right, 1 through
12. For example:
SOUR[n]:CURR 5 will be
SOUR4:CURR 5 for slot-1
SOUR7:CURR 5 for slot-2
voltage and current. They are shown in the following examples as floating
point numerical values, <fval>. For the Active Load modules, the values
are as follows:
Full-Scale Current:
HPAL: 30
LPAL: 15
Therefore, for an 750W Active Load module in slot 4, the command for
full-scale current would be SOUR4:CURR 30; for a 375W Active Load
module, it would be SOUR4:CURR 15.
